Coupler apparatus and communication apparatus

摘要

According to one embodiment, a coupler apparatus includes a coupling element, a ground plane, and at least one connecting element. The coupling element which is made of a tabular electrical conducting material and in which power feeding is performed to a reference point. The ground plane which is made of a tabular electrical conducting material and partially faces a part of the coupling element. The connecting element which is made of an electrical conducting material, disposed to the ground plane, contact to a metal member provided to a communication apparatus to face the ground plane, and electrically connects the ground plane to the metal member.
